Our today’s treat is Club3D’s Radeon HD 5870 Overclocked Edition. You might remember our review of our recent Club3D HD 5850 OC Edition graphics card review, and the card impressed us with silent operation. Good news is that it uses the same cooling solution we’ve seen on the HD 5850 OC card. As the name suggests, the card is overclocked and Club3D pushed the card from reference 850MHz to 875MHz for the GPU and the memory from 4800MHz to 4900MHz. Naturally, overclocking will help the card score better compared to reference but we were a bit disappointed with the factory overclock of only 25MHz, as the card is easily capable of running at even higher clocks.

Note that the reference HD 5870’s cooler is pretty good, unless of course you’re planning on overclocking the card; in that case the cooling can get pretty loud while trying to cool the GPU. That’s why Club3D chose to use non-reference cooling with heatpipe technology (4 heatpipes and aluminum heatsink). If that isn’t enough for you, know that Club3D used a different PCB that’s shorter than the reference. We found out that the PCB is actually the same one like on the Club3D HD 5850 OC Edition.

The HD 5870’s ticker is the powerful Cypress XT graphics processor with 1600 stream processor. The GPU packs 2.15 billion transistors on 334mm2 and is built in 40nm. It packs 32 ROPs and 80 texture units and its 1024MB of GDDR5 runs on a 256-bit memory interface.

Before we show you the card, it’s important to note that the chosen Club3D graphics cards, among which you’ll find out today’s test sample, come with a coupon for a free Dirt2 game, which can be installed via Steam.
